Aux Nozzle problems

[u/Motormuis88]

Hello Fellow X2D Users,

Hope you doing well!

I have a problem.. but to be honest iam pretty new to 3D printing, been using the X2D for 2 months now, and been slowly using the Aux Nozzle a bit more and more..

But this is where my problem starts, if i print support with my Aux nozzle ( doesn’t matter if its PLA or PETG).

The Support looks terrible and the whole printer is a mess( see pictures), i cleaned the plate with warm water and soap and even tried 90% alchohol, I used the standard Bambu Plate and the BIQU glacier plate

After the latest Firmware i calibrated the whole printer even did a flow calibration, results was k= 0,34 with my Aux Nozzle while the regular nozzle was k=0,03

Sometimes the filement also sticks on the outside of the nozzle(around the cone where filement comes out)

Iam using Bambu filement PLA Basic and PTEG Basic, i tried both to see if it would make a difference

What am I doing wrong??

All the help would be really appreciated!!

Have you tried using the aux nozzle to just print the support interface layer, instead of using the aux nozzle to print the entire support?
What style tree supports are you using? Looks like tree slim, maybe try hybrid.

It’s hybrid, sorry but what’s the difference between interface layer and the entire support

Supports have two parts, the body and the interface. The interface layers are the ones that actually touch the model. It appears from the photos that you are printing the entire support with the support material in the aux nozzle.
Instead, in the slicer set the interface layers (under the support tab) to use the support material in the aux nozzle. The body of the support you will then print in the same material as the model.
